Question 1. The number of transistor failures in an electronic computer may be considered as a random variable X drawn from the Poisson distribution. The numbers of transistor failures per hour for 96 hours are recorded in the table below. Estimate the parameter(s) of the distribution for X based on these data by using the method of maximum likelihood: i) Derive the maximum likelihood estimator for a random sample X1, ..., Xn; ii) Find the maximum likelihood estimate based on the observed values. Hourly failures(No.) Hours(No.) 59 27 ONHO 1 Co V Total=96
